题目：

In the year following an eight-cent increase in the federal tax on a pack of cigarettes, sales of cigarettes fell ten percent.  In contrast, in the year prior to the tax increase, sales had fallen one percent.  The volume of cigarette sales is therefore strongly related to the after-tax price of a pack of cigarettes.
 
The argument above requires which of following assumptions?

选项:

A、During the year following the tax increase, the pretax price of a pack of cigarettes did not increase by as much as it had during the year prior to the tax increase.
B、The one percent fall in cigarette sales in the year prior to tax increase was due to a smaller tax increase.
C、The pretax price of a pack of cigarettes gradually decreased throughout the year before and the year after the tax increase.
D、For the year following the tax increase, the pretax price of a pack of cigarettes was not eight or more cents lower than it had been the previous year.
E、As the after-tax price of a pack of cigarettes rises, the pretax price also rises.

An overly centralized economy, not the changes in the climate, is responsible for the poor agricultural production in Country X since its new government came to power. Neighboring Country Y has experienced the same climatic conditions, but while agricultural production has been falling in Country X, it has been rising in Country Y.

Which of the following, if true, would most weaken the argument above?
老师请问D是如何weaken原文的。是不是因为在相同气候下，不同的谷物产量不同，所以驳斥原文是X国经济体质导致产量不高?

Today's technology allows manufacturers to make small cars more fuel-efficient now than at any time in their production history.
我的逻辑-any time不对，是除了这个时间之外的其他时间，排除ABE；老师说CD中D的More fuel efficient，修饰问题，their指代car有指代问题；我选D的原因their指代manufacturers，语义也通，在制造业产量的历史中，今天的技术允许制造业制造更多小车；并且more修饰fuel-efficient，一般修饰都有就近原则，而且small用smaller肯定更好，而不是more small；C 中的those指代small cars，且没有歧义…选不出来；

A physically active lifestyle has been shown to help increase longevity. In the Wistar region of Bellaria, the average age at death is considerably higher than in any other part of the country. Wistar is the only mountainous part of Bellaria. A mountainous terrain makes even such basic activities as walking relatively strenuous; it essentially imposes a physically active lifestyle on people. Clearly, this circumstance explains the long lives of people in Wistar.

Which of the following, if true, most seriously weakens the argument?
谢谢解答。 做题时，认为几个选项都不合适，勉强选了B，也认为不那么对。对于C选项，看了OG的解释是说长期physically active lifestyle的人才长寿，那么C选项的确是正确的，但是原文中并没有“长期”这个观点，C选项也可以考虑为:正因为他们在中年或者退休后到了山城，才有了physically active lifestyle，使得他们长寿了，加强了观点。

The Quechuans believed that all things participated in both the material level and the mystical level of reality, and many individual Quechuans claimed to have contact with it directly with an ichana (dream) experience.
消除了it的问题排除AB；…C不应该用LAST; 因为只有俩个物体，latter对，by means of an ichana，这里不涉及到单复数，语义表达是通过，而不是因为，due to 不对；我理解老师的语义角度，这里另外一个迷惑我的考点是direct，我看到ACE用directly副词是对的，而BD不对 差异。我不想抬杠什么的。就是会不会考试题目有一些比较明显的差异结果排除了正确选项。有没有保险点的做法

Press Secretary:  Our critics claim that the President's recent highway project cancellations demonstrate a vindictive desire to punish legislative districts controlled by opposition parties.  They offer as evidence the fact that 90 percent of the projects canceled were in such districts.  But all of the canceled projects had been identified as wasteful in a report written by respected nonpartisan auditors.  So the President's choice was clearly motivated by sound budgetary policy, not partisan politics.
 
Which of the following is an assumption on which the press secretary's argument depends?
老师说B把原文的REASON补全了；我翻译的-最近取消的工程说明了为了惩罚反对党，但是原因是这些报告wasteful，由不参与政治的审计人写的；因此总统取消项目的原因是因为预算不是因为党内斗争；目前这个逻辑很完整，我自己脑补不出来什么assumption-如果选项中有好的assumption我直接选，也根据做题方法是可以想想排除他因也是一种assumption，选项中有证明Project本身不涉及党派斗争，就是排除他因，可以选；另外就是考虑到选项立场/发起人一致，也会有说服力；B中说了项目不是总统控制的；我当时第一反应是如果总统控制就应该不被reject，总统自己的项目当然要实施,那不被总统控制的项目被reject还是可能涉及了党派？我想问一下assumption的题目除了清晰的assumption/排除他因-这个类似于增加/立场角度/还有什么套路？另外就是我没懂B的逻辑

Combining enormous physical strength with higher intelligence, the Neanderthals appear as equipped for facing any obstacle the environment could put in their path, but their relatively sudden disappearance during the Paleolithic era indicates that an inability to adapt to some environmental change led to their extinction.
B选项我觉得appear 应该是过去式，因为后面句子的主要谓语动词为led，用了过去式，根据句意，前面半句Neanderthal 出现是为了面对困难，"出现"应该在"导致"之前，led是过去式，所以appear也应该是过去式。 2.E选项for doing也可以表示目的，为什么不对呢~

On Earth, among the surest indications of sunspot cycles are believed to be the rate that trees grow, as seen in the rings visible in the cross sections of their trunks.
我做题时候花了很久，看不懂，放弃，听了一下老师的做题过程，我自己看了半天看不懂文章，老师思考：看了句子，大概想说cycle是一个indications就像树桩上的年轮，AB排除因为on earth后又来一个修饰语，不太好，排除；as seen这里有一个并列，in the rings visible和among the surest indications并列，语义的确是这么说（虽然划线部分我没看懂这个cycle的indication/indication是速度），并且as seen in the rings,和as in the rings差别挺大的，没想着非要平行；排除C ;剩下DE，D中，believe动词发起者不明排除D； 对于我来说这道题，最困难的是找句意／找主语，what is believed?我觉得是sunspot cycles，但是among sth, sth are believed，那我要分开sunspot和cycles，但是没有逗号，我也认了，但是还是看不懂，换了一种理解，抛弃了among我理解“among the surest indications of sunspot cycle被认为是树生长的速度”…简化为indications被相信是速度…然后as seen。。。看不懂as seen想修饰谁，我就放弃随便选。我的问题是：应该如何去快速找到句意，未划线部分我理解年轮和树的年纪关系，但是前半句话不懂。

Several financial officers of the company spoke on condition that they not be named in the press reports.
开始一直没看懂，因为they，所以我以为不能修饰condition；很混乱，仔细看了press reports类似于发布会；that they not be named确定是condition没有被命名；翻译：公司的几个金融人员说了一些condition，这些condition没有被命名，在发布会上。然后我就不太理解应该的选项了。用that则为定语从句则their的指代问题，they的指代问题；排除ABC，DE是一个of结构后面应该是一个名词吧；政府官员说了一个“没有被正式命名的一个条件/状况”；纠结DE.正确答案早被我排除了

Studies in restaurants show that the tips left by customers who pay their bill in cash tend to be larger when the bill is presented on a tray that bears a credit-card logo. Consumer psychologists hypothesize that simply seeing a credit-card logo makes many credit-card holders willing to spend more because it reminds them that their spending power exceeds the cash they have immediately available.

Which of the following, if true, most strongly supports the psychologists’ interpretation of the studies?
老师您好，我选错了E选项，然后B选项是不是反对了和原文相反的东西，所以正确呢？麻烦您解释一下
